[Paraview] moving streamlines with flow

[Whitehouse, Paul L. (GSFC-5520)]

Jan,

This will straddle the boundary of ParaView and Plasma Physics: first, this is a good lesson in the non-reality of the “frozen-in” condition for field lines – they are just integral lines and something to always keep in mind; second, I think you would have to specify your own list of seed points and have them advect with the plasma over each time step. You would have to use a zero radius and one streamline from each – otherwise you would get something different each time that wouldn’t look frozen-in.

Subject: [Paraview] moving streamlines with flow

Hello,

I am running simulations of magnetized plasma flow through a
computational domain. In the simulation the magnetic field lines are
moving with the flow. When generating an animation over different time
steps (frames), however, the streamtracer uses the same seeds for each
frame, and hence the resulting impression is that the field lines do not
move in time.

Would anybody have an idea on how to accomplish moving field lines?

Thank you!

Jan
